B<name> is the B<friendlyName> to use for 19the supplied certifictate and key. B<pkey> is the private key to include in 20the structure and B<cert> its corresponding certificates. B<ca>, if not B<NULL> 21is an optional set of certificates to also include in the structure. 22 23B<nid_key> and B<nid_cert> are the encryption algorithms that should be used 24for the key and certificate respectively. B<iter> is the encryption algorithm 25iteration count to use and B<mac_iter> is the MAC iteration count to use. 26B<keytype> is the type of key. 27 28=head1 NOTES 29 30The parameters B<nid_key>, B<nid_cert>, B<iter>, B<mac_iter> and B<keytype> 31can all be set to zero and sensible defaults will be used. 32 33These defaults are: 40 bit RC2 encryption for certificates, triple DES 34encryption for private keys, a key iteration count of PKCS12_DEFAULT_ITER 35(currently 2048) and a MAC iteration count of 1. 36 37The default MAC iteration count is 1 in order to retain compatibility with 38old software which did not interpret MAC iteration counts. If such compatibility 39is not required then B<mac_iter> should be set to PKCS12_DEFAULT_ITER. 40 41B<keytype> adds a flag to the store private key. This is a non standard extension 42that is only currently interpreted by MSIE. If set to zero the flag is omitted, 43if set to B<KEY_SIG> the key can be used for signing only, if set to B<KEY_EX> 44it can be used for signing and encryption. This option was useful for old 45export grade software which could use signing only keys of arbitrary size but 46had restrictions on the permissible sizes of keys which could be used for 47encryption. 48 49=head1 NEW FUNCTIONALITY IN OPENSSL 0.9.8 50 51Some additional functionality was added to PKCS12_create() in OpenSSL 520.9.8. These extensions are detailed below. 53 54If a certificate contains an B<alias> or B<keyid> then this will be 55used for the corresponding B<friendlyName> or B<localKeyID> in the 56PKCS12 structure. 57 58Either B<pkey>, B<cert> or both can be B<NULL> to indicate that no key or 59certficate is required. In previous versions both had to be present or 60a fatal error is returned. 61 62B<nid_key> or B<nid_cert> can be set to -1 indicating that no encryption 63should be used. 64 65B<mac_iter> can be set to -1 and the MAC will then be omitted entirely. 66 67=head1 SEE ALSO 68 69L<d2i_PKCS12(3)|d2i_PKCS12(3)> 70 71=head1 HISTORY 72 73PKCS12_create was added in OpenSSL 0.9.3 74 75=cut 76
